How to Copy LocalStorage in JavaScript?

Estimated read time 1 min read

You can copy the contents of local storage in JavaScript using the following code:

function copyLocalStorage() {
  var backup = {};
  for (var i = 0; i < localStorage.length; i++) {
    var key = localStorage.key(i);
    backup[key] = localStorage.getItem(key);
  return backup;

This code uses a for loop to iterate over all the keys in local storage and stores the key-value pairs in a JavaScript object. The object is then returned from the function and can be saved as a backup or used for other purposes.
